A civil air ensign is a flag (or a variation thereof) which represents civil aviation in a country or organization. Typically, it is flown from buildings connected with the administration of civil aviation and it may also be flown by airlines of the appropriate country.^[1] A civil air ensign is the equivalent of the civil ensign which represents merchant shipping. Not all countries have civil air ensigns and those without usually fly their national flags instead.
